Adjustable wishbone blade, especially for rail vehicles

The invention relates to an adjustable wishbone blade, in particular for guiding a bogie wheelset for high-speed rail vehicles, whereby the longitudinal members of the bogie frame have springs on the axle box the wheelsets are supported.

It is known (DBP 847-918) to design the axle bearing housing, which is guided by means of axle guide blades, to be adjustable on the longitudinal side, by the wishbone blades at one end or at both ends with one side, in the known embodiment with arranged between the handlebar blade and the fixed bracket or the axle box, opposite the axle guide blade through Arrangement of a transverse groove immovable supplement are provided, the steering arm blade facing away and the fixed bracket or the side facing the axle bearing housing is toothed, the toothing of the shim in the in the axle bearing housing or toothing located in the fixed bracket engages. The wheel set can be fixed by connecting the wishbone ends with the

Supplements can be screwed onto the axle box or the fixed bracket and assembled into a unit using fastening screws are.

By guiding the wheel sets with wishbone blades that are rigid, i. H. Free of play and friction with the axle bearing housing are connected and of which at least one wishbone blade on each side of the wheelset is inflexible in the longitudinal direction is connected to the bogie frame (according to DBP 834 256), is an extension of the sine curve of a rail vehicle bogie bring about a smooth running of the car at the previously driven, relatively high speeds guaranteed. The wheel tire wear, especially the Wheel flange wear, however, was relatively large when driving through curves.

According to the latest knowledge of the running technology of bogie vehicles a wheel profile with a steeper cone must be used to achieve a run of about 500,000 km. The use of this profile of the running wheels of rail vehicles presupposes that the wheelset has a resilience in the longitudinal direction of the carriage an adjustment for the sheet travel is given. The wheelsets in the

known bogies according to DBP 834 256 are rigidly guided by axle links; a rigid guidance of the wheel sets includes one Adjustment option for sheet travel.

The object on which the invention is based is, by installing an adjustable steering arm blade, in particular for rail vehicles, to provide a bogie that allows the carriage to run smoothly at maximum speed, i. H. at 200 to 250 km / h when using wheels with a steeper taper, with one of the known bogies according to DBP 834 256 should be assumed and a self-adjustability when cornering as well as a stable run in the Straight lines without exhausting the track play can be guaranteed target. It should be possible to convert the bogies currently on the market without any significant effort.

This is achieved according to the invention in that an intermediate layer, designed as a rubber-metal element, is attached to the axle bearing after the center of the bogie to above and below the wishbone and arranged by means of a collar and one with this screwable clamping nut with a certain Torque can be connected to a unit,

In an embodiment of the invention, a mounting metal ring is centered on the rubber layer of the upper rubber-metal element vulcanized on, which, during assembly, is centrally attached to a recess that is open at the bottom on the collar of the collar can be fitted as a centering aid.

According to the invention, through the insertion of elastic intermediate layers between the steering arm blade and the axle bearing housing a resilience of the axle steering in the longitudinal direction with an adjustment option for sheet travel and so that a considerable improvement in the quality of the carriage can be achieved at speeds of more than 200 km / h, with a steeper taper profile a reduction in the
